Baby Sign Language: Does It Work?

What if babies could tell us what they want, before they start crying for it? Bring in baby signing, a system of symbolic hand gestures for key works such as “milk,” “hot” and “all gone” that are taught to hearing babies as a way to communicate before they can talk.

The sign for milk, for example, is made by opening and closing the hand, while the sign for “more” by tapping the ends of the fingers together.
